I don't see a lot of improvement in those pics. The before pics seem like the hair is darker and perhaps moist allowing it clump together and show more scalp. The after pics hair seem lighter in colour and dryer. Also looks like they combed it differently in the after pics and perhaps combed over some exposed scalp. But it wouldn't hurt to try these herbs if you can get them and see for yourself. Maybe it takes more time to fill in.

Yes the improvement is minimal but I do see improvement on close inspection at least we know it's not a scam if it was they would have globbed the after pics with toppik lol I hope to run this experiment soon I t would only be roughly 100 bucks for 6 months if you bought bulk herb powder on amazon
